The application of multi-scale modeling technology in artificial bone graft

Abstract

In view of the preparation of the individual implants for artificial bone grafting procedures, this paper puts forward a new kind multi-scale modeling idea for artificial bone. First, build up the corresponding macro-level CAD model of the patients based on CT data; Secondly, realize the bone's internal property by analyzing the gray-scale of the patients' CT image and build up the micro-scale model in Pro/E; Finally, obtain the multi-scale CAD model of the artificial bone that match with the remaining parts by combing the macro-scale and micro-scale model and convert it into STL files to complete the preparation of implants. The further mechanical analysis was finished for the structure selection of multi-scale implantation. © 2011 Springer-Verlag.
